Method comprising: designing a gear in a software-based computer-aided manner in order to obtain a function-oriented geometry, using a software-based computer-aided method for ascertaining a theoretically producible gear geometry corresponding to or an approximation of the function-oriented geometry), providing production data representing the theoretically producible geometry, machining a gear using the production data in a CNC-controlled processing machine, measuring the gear to obtain an actual data set of the gear, carrying out a comparison of the actual data set with the production data in order to ascertain at least one correction variable, using the correction variable in order to ascertain corrected production data from the production data or carry out a machining correction in the processing machine, and post-machining the gear using the machining correction or using the corrected production data in order to machine at least one additional gear in the processing machine.

The present disclosure includes a part hold-down assembly for retaining an oversized part. The part hold-down assembly is aligned along a central force axis and applies a downward force onto the part. The part-hold down assembly includes a top plate, a bottom plate, and a compression assembly extending between the top and bottom plates. The compression assembly includes two, parallel biasing assemblies that extend along compression axes that are parallel to but offset from the central force axis. Each biasing assembly including an upper collar, a lower collar and a resilient biasing member, in one embodiment in the form of a coil spring, retained between the upper and lower collar. The parallel biasing assemblies are positioned on opposite sides from each other about the central force axis, and may be spaced away from the central force axis an equal distance.

A workholding apparatus (10) wherein a draw bar (22) effects chucking and de-chucking of a workpiece (W) and wherein un-seating of the workholding apparatus is effected by piston-like mechanisms (30) located in a machine spindle (2).
